1 #include <iostream> 2 #include<cstdio> 3 #define ll long long 4 using namespace std; 5 ll a,ans,d; 6 ll gcd(ll a,ll b) 7 { 8 if(b==0) 9 return a; 10 gcd(b,a%b); 11 } 12 int main() 13 { 14 int n,flag; 15 while(~scanf("%d",&n)) 16 { 17 if(n==0) 18 break; 19 ans=1; 20 flag=1; 21 for(int i=0;i<n;i++) 22 { 23 scanf("%lld",&a); 24 d=gcd(ans,a); 25 ans=ans/d*a; 26 if(ans>=1000000) 27 { 28 flag=0; 29 continue;//注意是continue而不能是break 30 } 31 } 32 if(!flag) 33 printf("Too much money to pay!
